If you found out you were infertile and thus enable to conceive a child, would you get sad? Knowing that you cannot ever have a biological child? Would you not care?
Nothing because as of now I never want to father a child I'd just keep living my life and doing as I please, eliminating that possibility from my life completely.
Hm. My first thought was "I don't care because I'm gay and I don't want kids anyway" but the more I think about it the more I'm not so sure. What if one day I were to change my mind about not wanting kids (or about being gay hehehe )?
Children will never be in the cards for me, so I wouldn't care. (And, supposing that they were, I absolutely wouldn't ever need them to be mine biologically.)
